stirred and kept well pullverized on top in order to 

 prevent drying out. In light soil an application of fertil- 

 izer, should be made two or three months after planting, 

 using y 2 'lb. per tree of formula No. 1. This should be 

 scattered around the trees not closer than 6 inches to 

 the trunk, and the application should be repeated every 

 three months during the first year. If plants are used for 

 wind protection they should be cultivated and if cover 

 crops are planted, strips on each side of the citrus rows 

 or circles around each tree, should be kept iclean. At 

 the end of the rainy season the cover crops should be cut 

 and used as a mullch immediately around the trees, and 

 the middles should be plowed and cultivated often 

 enough to prevent the moisture from escaping. 



During the first three years this treatment may be 

 kept up. Fertilizers like formula No. 1 should be applied 

 from two to four times per year gradually increasing the 

 amount from 2 to 6 Ibs. and gradually increasing the 

 width of the circle and distance from the trunk of the 

 tree. On flight soil the first ieover crop should be fertilized 

 with 300 Ibs. to 600 Ibs. of formula No. 4, and if a large 

 portion of the crop is us>ed for mulching the trees less 

 fertilizer will be needed for them. With heavy growth 

 of cover crops plowed in every year, formula No. 3 

 should be used for the trees after the second year. The 

 kind of formula to use can largely be determined by 

 the collor of the leaves, a dark green color and vigor- 

 ous growth indicates an abundance of nitrogen, whereas 

 a yellowish color indicates lack of nitrogen. On heavier 

 soil where ordinarily no fertilizer is needed during the 

 first 3 to 4 years, formula No. 3 can profitably be used if 

 the trees show a tendency towards gumming.
